Xen Migration Errors
by Chris Vaughan
Hi,
I am trying to perform a live xen migration and in the xm list it's saying
that it transfers but when I try and console onto the node it looks like it
does a kernel dump.
Here is my xend.log:

Any help would be appreciated. Both distros are running FC5. Does the same
hardware, kernel and image need to exist on the host and the migration
destination?
Thanks,

xenguest-install.py nfs problems
by Tom Spec
!-- DIV {margin:0px;}-->!-- DIV {margin:0px;}-->When I run xenguest-install.py on FC5, it always gives me the following error after "What is the install location?":
Invalid NFS location given
I have tried two different methods that work for me for regular installations,but I can't get this script to work.
1) Specify the location that contains the Fedora Core .iso files
2) Specify the location that contains the "Fedora" directory (and subsequently all the RPMs)
Can someone tell me exactly what xenguest-install.py is looking for in an NFS install location?
Note: It does seem to be mounting the NFS directory, it's just that it tells me it's invalid.
Any help would be appreciated.

Xen guest on RAID5 LVM (install problem)
by Robert Mortimer
I am trying to install a Xen FC5 client on my FC5 machine.
I have a single SATA boot drive with a standard FC5 install
I have a RAID5 array of 3 SATA disks for my VM's
I run the install script but and specify the path to the logical Volume when
prompted
All goes well until the script tries to format the partition.
If it has already been mounted it will recognize the fact
When it goes to format I get the following just after the network setup
loader received SIGSEGV!. Backtrace:
[0x8049865]
[0x754420]
[0x8063ca0]
[0x805e5e1]
[0x804ad21]
[0x80cae75]
[0x8048131]
install exited abnormally
sending termination signals...done
sending kill signals...done
disabling swap...
unmounting filesystems...
/proc done
/dev/pts done
/sys done
/tmp/ramfs done
you may safely reboot your system
If I format the LVM with ext3 I get to the partitioning but it then craps
out on the format

xen boot problem
by Ron Wahler
with FC5 2.5.16.1-2133 and xen 3.2
to get zen to boot out of grub I had to turn off the xend on startup with
chkconfig and
then Zen would come up into X Windows. You then have to setenforce=0 and
then start
xend.
chkconfig --level 345 xend off
....
boot xen into xwindows
.....
setenforce=o
xend start
...
now xen is ready for a guest.
